Web services are generally self-contained, self-describing, modular software applications that can be published, located, and invoked across the Internet or other type of network. Current web services perform various computing and processing functions including simple requests and complicated business processes. Once web services are deployed onto the Internet, for example, other applications, including other web services may locate and invoke deployed web services. Typically, web services make enterprise application integration simpler and less expensive and open new opportunities by increasing user reach and extending business partnerships.
